Experience gaining above 90 level

oHi

It's very boring to level after my char got 90th level coz it is very slow - i have to grind triple as much to get the same result that i got 7 levels ago

I konw that there are maps that give more experience gain but these maps are of 75th level of the monsters and more experience gain doesn't help when my char is 91th level. The difference between 75 and 91 levels is killing addition experince gain on such maps

Thanks
